Title: Zener diode
Inventor: FUJII HIDEHARU
IPC: H01L29/866
Filed: 1981-08-28
Abstract: PURPOSE:To stabilize Zener voltage, and to reduce cost by forming a deep P type auxiliary layer, which has dielectric resistance higher than a P<+> Si layer, into the P<+> Si layer, coating a shallow P layer outside the auxiliary layer and the fringe section with SiO2 and shaping an electrode, the principal ingredient thereof is gold, onto the auxiliary layer and the SiO2. CONSTITUTION:An extremely shallow P<+> layer 3 is shaped circularly to an N++ epitaxial layer 1 on an N<+> type Si substrate 2. A P type guard ring 4 is formed to the fringe of the P<+> layer 3. The four P type auxiliary layers 12 are molded into the layer 3 in depth far deeper than the layer 3, the distribution of impurity concentration is made gentle in the depth direction, and dielectric resistance is made larger than a shallow junction section. The surface is coated selectively with an SiO2 5 including the boundary of shallow and deep junctions, an Au electrode 13 containing Ga is formed and ohmic property is improved, and an Ag layer 13 and an Ag bump electrode 9 are stacked. When normalcy, currents flow through the shallow P-N junction and desired Zener voltage is obtained, when surge, large currents flow through the deep junction and do not break through the junction because the junction is deep even when an Au-Si eutectic is generated. According to this constitution, Zener voltage is stabilized, and yield is also improved.

Title: Magnetic disk device
Inventor: TERAMURA MASAYASU
IPC: G11B19/20
Filed: 1984-06-28
Abstract: PURPOSE:To increase the lifetime of a driving system and at the same time to reduce the power consumption by detecting the shift of a clamp lever containing a clamping mechanism which revolves a magnetic medium and therefore giving a driving command to a spindle drive system. CONSTITUTION:A clamp lever 5 is shifted toward an arrow after a diskette 1 is inserted along a guide 2 as shown by dotted lines, and a sensor 9 detects instantaneously the shift of the lever 5. Therefore a switch 101 is turned on through a switch control circuit 10, and a motor 6 starts its revolution. At the same time, a spindle 3 is also turned. Then a clamping mechanism 4 moves to oppose to the spindle 3. Thus the spindle 3 is revolved and at the same time set opposite to the diskette 1. This facilitate easy positioning of the spindle 3. At the same time, the spindle 3 is revolved only when the lever 5 operates. This can reduce the power consumption of a spindle drive motor and also increases the lifetime of the spindle drive system.

Title: Internal combustion engine piston
Inventor: FUKAZAWA KOUJI
IPC: F02F3/00
Filed: 1977-11-09
Abstract: PURPOSE:To provide a slipper type piston with both adequate elasticity and rigidity by making the thickness of either a thrust side or non-thrust side flange portion than that of the other portion. CONSTITUTION:In a slipper type piston 1, in which a skirt section 11 is formed  with notches C to leave flange portions 12 on the thrust side T and non-thrust side  U, the thickness D1 of the flange portion 12 on the thrust side T is made greater  than the thickness D2 of the flange portion 12 on the non-thrust side U. With this  structure, when the clockwise moment M is momentarily increased with increase of the gas pressure Fg at the time of the power stroke, the flange portion 2 on the  thrust side T, which has a greater thickness D1 and has sufficient rigidity, can prevent the tilting of the piston 1 to prevent the upper end 14U of the piston on the  non- thrust side U from striking the cylinder 14.
Patent JP-S62290230-A (JP)
Title: Line access system
Inventor: TERAOKA FUMIO
Filed: 1986-06-10
Abstract: PURPOSE:To prevent packets from colliding and to shorten response time by setting different addresses to each station in a bus type network, detecting said addresses and setting queue time in terms of transmission based on the difference between the address of a transmission station, which is transmitted just before, and the address of a self station. CONSTITUTION:If a line is busy, A station, which is about to transmit, waits until the line is unengaged. When the line becomes unengaged, a queue time setter 5 calculates the difference between the self station address (a) and the transmission station address (x) for the packet transmitted just before, sets the queue time corresponding to the difference (s), and gives said time to a transmitter 3, which is on standby. On the other hand, when the line is unengaged, such judgement is made whether that state continues more than 4 dsec. If so, transmission starts. If the line is under high load, packets never collide, and the response time is shortened.

Filed: 1991-06-06
Abstract: PURPOSE:To form, with good reproducibility, an ohmic contact, without executing an alloying treatment, in a P<+> type GaAs layer formed by an ion implantation method. CONSTITUTION:<q>Be<-> ions are implanted into a semi-insulating GaAs substrate 1; an ion-implanted layer 2 is formed. An SiO2 film 3 is deposited on the surface of the GaAs substrate 1 including the region of the ion-implanted layer 2; a heat treatment is executed at 750 to 850 deg.C; an As-Be transformed layer 4 is formed on the surface of the ion-implanted layer 2 directly under the SiO2 film 3; and at the same time, the ion-implanted layer 2 directly under the transformed layer 4 is converted into a P<+> type layer 5. The SiO2 film 3 and the transformed layer 4 are removed by using a hydrofluoric acid-based aqueous solution; the P<+> type layer 5 is exposed. An ohmic metal such as Au-Zn 6 or the like is deposited on the surface of the exposed P<+> type layer 5. Since the concentration of holes on the surface of the P<+> type layer 5 can be increased, a good ohmic contact can be obtained with good reproducibility without executing an alloying treatment (without an alloy).

Title: Medical stent
Inventor: YOZEFU FUROMENBURITO
IPC: A61M29/02
Filed: 1994-05-26
Abstract: PURPOSE: To guarantee an organ to have a larger diameter by equippign a stent with a spiral coil made from a two-square memory alloy and a super- elastic state within a physiologic range accepted by some organs and a pliable state in which the diameter of the stent is smaller than the critical diameter although the diameter of the stent is larger than the critical one. CONSTITUTION: A stent consisting of a band 12 made from a two-square memory alloy is conditioned in a super-elastic state so as to have a form of a spiral coil 14, the diameter of which is close to that of a tubular organ. In a pliable stare the stent is conditioned so as to have a form of a spiral coil 16 in which the diameter of the stent is narrower than that in the super-elastic state. When the temperature of the band 12 rises higher than the first transfer temperature, the band 12 instantly changes into the form 14 that it should have in the super- elastic state. When the temperature drops lower than the second transfer temperature, the diameter of the stent becomes narrower and it takes the form 16 in the pliable state. When a catheter is taken into a tubular organ and heated, the diameter increases, pressurizing the wall of the organ.

IPC: H02P6/06
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To stably operate a pump for jet generating bathtub by accurately recognizing the position of the rotor of a motor by avoiding noise by outputting a driving pulse of a prescribed pattern corresponding to a positional input from a comparator to a switching element by using a microcomputer. SOLUTION: The microcomputer 1 of a pump drive controller 11 is set in such a way that, after the microcomputer 1 outputs a driving pulse to a switching element 3 based on a positional input from a comparator 4, the microcomputer 1 maintains the output without performing positional judgment on the rotor 32 of a motor for a fixed period of time and, after the fixed period of time has elapsed, restarts the positional judgment and outputs a driving pulse of a prescribed pattern corresponding to the positional input from the comparator 4. Therefore, more accurate positional judgment can be performed on the rotor 32 and a pump 31 can be operated stably by avoiding the influence of switching noise which is generated when the switching element 3 is turned on/off.
